A Bright Moving Orb

Photo date: November 18, 2014. Photographer: Mark Mahin.

In this indoor photo of a featureless wall, we see what photographers call a "ghosting" effect that is a sign of rapid movement. Given the camera's shutter speed of 1/2000 of a second, an effect like this could only be produced by a rapidly moving object. The apparent size was about the size of a basketball, and the orb was about 8% of the total photo height.

 Air quality: 120/2, Good. Reflective objects nearby: none. There were no lights sources contributing to the photo area, other than the camera flash. No orbs were seen in photos taken at the same place and angle, shortly before and shortly after this picture was taken, which argues against any dust explanation. No flying insects were observed at the photo site.
